rxswift

In the previous article, we analyzed the entire subscription process in Rxswift. Before the start of the transformation operation, the first to understand the concept of Chu sink, unclear students can look at an analysis of an article. In a nutshell, a sink convection operation occurs before each subscription operation. If the flow in the RX is treated as water, then the sink is equivalent to the strainer of each water faucet, and the final processing

TableView on A, preface the river is said now to quickly learn swift, is going to be swift world. In the case of small changes in the API, Swift as a new language, set the director of the family, the general code is really better than OC to use more than the old have heard the concept of MVVM and responsive functional programming, Microsoft is really bad. I have nothing recently, I came to the pit. second, the way of learning to refer to someone else to write some blog, for the concept of a fir

RxSwift: Schedulers details, rxswiftschedulers Scheduler In short, Scheduler is the context of process execution (or the context of program execution ). Context can be a thread, a dispatch queue, or NSOperation in OperationQueueScheduler. Here is a good example of how the dispatcher is used: We can see that we may make network requests in the backend Scheduler and then cache data. And pass the data to all subscribers. Most of the time, it will retu

Why use Rxswift?Most of the code we write involves responses to external events. When the user clicks on the action, we need to write an @IBAction event to respond. We need to observe notifications to detect when the keyboard is changing position. When the network requests the response data, we must provide closures to execute. We use it KVO to detect changes in variables. All of these different systems add unnecessarily complexity to our code. Wouldn

1, if we want to implement, click on the view can let the text box in the view stop editing, we can do this in the storyboard to drag a gesture out, and then in referencing Outlets collection to go and view to the association. And then we can write

This is a creation in Article, where the information may have evolved or changed. An interview with Chris Lattner (next) Topic What is Swift's ambition in terms of Server and operating systems? Swift and objective-c love and hate? What are the original ideas of Swift's father for RxSwift and ARC? Will the language continue to run with Swift's father?

problem, the interviewer is evaluating your knowledge of the various message patterns used in iOS.The expected answer:Both are methods of establishing relationships between objects. A delegate is a one-to-one relationship, an object implements a delegate protocol, another uses it and sends a message to it, assuming these methods are implemented because the recipient commits to abide by the protocol. KVO is a many-to-many relationship where an object can play a message and one or more other obje

Here I'll talk about how responsive programming (reactive programming) pushes asynchronous programming to a whole new level.Asynchronous programming is really hard.Most of the speeches and articles on responsive programming are showing how amazing the reactive framework is, giving some examples that can be done in very complex situations with just a few lines of code. An example? I have a code for a rxswift-based chat program here:Socket.rx_event .
